Theta not found- theta X - linux 22.04

cfxd · July 3, 2025, 3:40pm

Hello,

We have a theta X (software version 2.71.1 -latest-)
And we have either a laptop (without NVIDIA) on ubuntu 22.04 or a Jetson Orin Nano (Jetpack 6.1) on ubuntu 22.04.
We notice exactly the same output on both.

We followed this guide: Linux Getting Started
as well as this one: USB API and Linux
and finally for the jetson: Setting Up NVIDIA Jetson Nano with RICOH THETA Z1 and X

We do not observe the same scenario at all when plugging the camera. (No pop-up screen)

We first tried without v4l2 installed.

lsusb
Bus 003 Device 012: ID 05ca:0373 Ricoh Co., Ltd RICOH THETA X

We notice that we have 05ca:0373, not 05ca:2715 (but we have 05ca:2717 on the Jetson Orin nano, after a few tweaks we do not remember the process of)

gphoto2 works well, we can take video etc.
However, we can’t start gstviewer :
./gst_viewer
THETA not found

Since the plan is to use theta X with ros2, we need gst.

The installation process:

No LSB modules are available.

installing v4lt2, setting ricoh theta X in live streaming:

v4l2-ctl --list-devices
RICOH THETA X: RICOH THETA X (usb-0000:00:14.0-4): /dev/media1

and ./gst_loopback
THETA not found

What is the issue? I do not see any thread covering this particular problem.

Thanks for your attention,
Best regards

do you have the camera in live streaming mode prior to running ./gst_loopback. You can either use the buttons on the camera or the USB API to change the camera mode.

cfxd · July 3, 2025, 7:15pm

Hello Craig,

Yes i tried all modes (camera, video, live streaming), as the last one was indicated in one of the mentioned links.
Each was tried at least once both on the computer and the jetson orin nano for both gst_viewer et gst_loopback.
I only used the buttons on the camera and not any USB API though. Could that have any incidence?

The problem is still ongoing

craig · July 9, 2025, 1:55pm

do you have another version of libuvc installed on your computer?
do you have a different Device ID when the camera is in live streaming mode versus camera mode?

cfxd · July 10, 2025, 3:13pm

Hello Craig,
Excellent questions. I didn’t think about mentioning it.
Yes i had a previous version of libuvc installed on my pc (Jetson i do not recall)
I installed the repos, realised I had several versions, removed everything (sudo apt remove libuvc + manually removed directory mentioning libuvc) before re-doing the whole process from scratch.
now (on both jetson and PC):
find /usr -name "*libuvc*"

/usr/local/include/libuvc
/usr/local/include/libuvc/libuvc.h
/usr/local/include/libuvc/libuvc_config.h
/usr/local/lib/pkgconfig/libuvc.pc
/usr/local/lib/libuvc.so.0.0.6
/usr/local/lib/libuvc.so.0

/usr/local/lib/cmake/libuvc/libuvcConfig.cmake
/usr/local/lib/libuvc.so
/usr/local/lib/libuvc.a

On jetson

in camera mode:
Bus 002 Device 003: ID 05ca:0373 Ricoh Co., Ltd RICOH THETA X

in video mode (de-plugged, re-plugged):
Bus 002 Device 004: ID 05ca:0373 Ricoh Co., Ltd RICOH THETA X

in streaming mode (setting auto-switch to streaming when connected, the camera does the switch correctly -re-plugging-):
Bus 002 Device 006: ID 05ca:2717 Ricoh Co., Ltd RICOH THETA X
If I remember the community comments correctly, I should have 2713 or 2717, am I correct?

yet with v4l2-ctl --list-devices:

RICOH THETA X: RICOH THETA X (usb-3610000.usb-1.1):
	/dev/media1
Cannot open device /dev/video0, exiting.

./gst_viewer --> THETA not found
./gst_loopback --> THETA not found

Is there anything of notice here?
Thanks for your assistance!
